DIAMOND GAS CRYSTAL against its type
It is one of 33 LNG carriers here under the Singapore flag, 6.1% of the 538 on the register. The returns for 2022–2025 all give SINGAPORE as port of registry.
Its 12,079 t of CO₂ for 2025 is 44% below the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 482.2 kg CO₂, close to the type median of 533.6 kg. It logged 1,956 hours at sea against a median of 2,940 hours for its type that year. 2.0% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 4 years with reported emissions, the highest was 2024 (31,412 t) and the lowest 2022 (11,904 t). Of the 7 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 1.5% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 61.5% and CO₂ per nautical mile rose 8.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
